To all whom it may' concern:

lie it known that l, JOHN ROBERT Gorman, a subject of the King of Great Britain, and a resident of Greensboro, in the county of l Guilford and State of North Carolina, have i made certain new and useful Improvements l in Reversing Mechanism, of which the following is a specilication. Y

rll`liis invention is an improvement in sin i gle belt reversing ear mechanism for WashF ing machines; an consists in certain novel j constructions and combinations of parts as l will he hereinafter described and claimed; I

lln tlie drawing Figure l is an elevation of one end of the machine. Fi 2 is a frontelevation of the machine part y in section. Fig. 3 is an elevation of the end of the machinel opposite that shown in Fig. 1, and Fie. 4 is a detail View showing the band pu leys, the' worm, and the intermediate sleeve.

lBy my invention l seek to provide a novel construction o f gearing for a washing niacliine whereby the machine may be revolved oneA direction and then reversed and revolved a corresponding number of revolutions in the opposite direction, and in doing this l seek to drive'the revolvii'ig portion of the machine in one direction frbm one end and inthe otherdirection from the opposite end thus reducing the strain and lessening the tendency of the parts to become twisted direction of the revolution as sometimes-occurs where the revolving parts are driven the machine.

In the construction shown the-revolving Washer A is provided at one end with a truI1- nion A', and at its other end with a trunnion A2. The trunnion A has xed to it a gear B and the trunnion A2 has xed to it a gear C, and these gears are meshed respectively, with gears Bf and C driven in the manner more fully described herein` after. y

A' shaftl) extends from end to end of the machine and is provided at one end with a pinion D geared by-r an intermediate gear 'B2 with the gear B so thepinion D when turned will operate to turn the gear B and thus turn the revolving washer in one direction. At the opposite end of the shaft D from the pinion Dl provide band pulleys 1, 2 and 3, the pulley 3 having a pinion C2 meshing directly with the gear C and operating when turned to revolve the revolving washer inl a direction the reverse of that in which it is revolved by the pinion D. These pulleys l, 2 and 3 all encircle the shaft il),

.the pulley 2, being secured on the said shaft by set screws 20, and the pulleys 3 journaling on the tube section E, which is iitted on i the shaft D as shown in Fig. 2. It will be understood that means are provided for g turning the pulleys 2 and 3 alternately, and

in doing this l provide in connection with the pulley l, a single belt F, which runs at all times upon the pulley l, and upon one or the other of the pulleys 2 or 3. The pulley l operates upon a Worm G, which meshes with a worm wheel H having a pin l oper ating upon the sliding shifter d to move the `shifter and move the belt between its (liderpulley.

In connecting the shifter pulley with the worm wheel, l prefer to provide the tube E fitting on the shaft D and coupled at one end by a' slipcoupling with the shifter pulley l, and at its other end with the worm wheel Gr, the slip coupling being edected by notching one of the parts at K and providing the. adjoining part with a tongue l to enterI said notch as best shown in Fig. Il of the drawing. It is preferred to make the sleeve of brass for durability, and to. provide the slip couplings as shown, for special oiling urposes, this construction facilitating the ceding of oil to the shaft D by the coup` lings between the parts l and @,and the part E.

ln the operation of the described con-l struction, it will be noticed l provide the washing machinewith a revolving washer and with gearing at its opposite ends for lturning the revolving washer, said gearing los chine as Will be understood from the foregoing description.

In the construction shown it will be noi for supporting the several band pulleys, one

of which drives the said shaft, and the other of which is mounted on the shaft and opby the drive shaft, also that the drive shaft supports the worm and the sleeve connection by which said worm is driven from the shifter pulley.

--I claim 1. In an apparatus substantially as deing in connection with said lrunnions, a drive shaft, means operated by said shaft and operating upon one end trunnion to turn the revolving part in one direction, a band pulley fast upon said drive shaft, a pulley loose on the drive shaft, a sleeve connection carried by said pulley and encircling I the drive shaft, and 'a worm encircling the i drive shaft, and driven by said sleeve connection, a pulley along side the said loose pulley, means operated by said pulley and operating upon the other end trunnion of the revolving part to turn the revolving art in the opposite direction, and a belt shlfter 1 mechanism operated by the worm, substantially as set forth.

2. In a machine substantially as described the combination of a part to be driven, a drive shaft, a worm thereon, a shifter pulley on the drive shaft, a pulley on the shaft on the outer side of the shifter pulley and I fast on the shaft, a connecting sleeve beerates to drive the gearing at the opposite i end of the machine from that directly driven i tween the shifter pulley and the worm, a pulley on the opposite side of the shifter pulle` from the shaft pulley and journaled on the connecting sleeve, gearingbetween the latter pulley and one 'end of the part to g be driven, gearing between the opposite end of the part to be driven and the drive shaft,

and shifter mechanism operated by the scribed the combmation of a revolving part having trunnions at its opposite ends, gearworm, substantially as set forth.

3. The combination substantially as hei-cin described of a drive shaft, a pulleyv fast thereon. a shifter pulley loose ou the drive shaft along side the fast pulley, a sleeve coupled at one end to the shifter pulley, and

i extending thence alongr and surrounding the drive shaft, a worin coupled to the other end of said sleeve, a pulley journaled on the sleeve aloner side the shifter pulley, and

shifter mechanism operated by the worm,

sul'istanlially as set forth.
